Specification of Letters Patent.

Patented July 2-2, 1919.

Original application filed May 15, 1917, Serial No. 168,358. Divided and this application filed February 28, 1919. Serial No. 279,870.

To all whom it may concern:

Be it known that I, EUGENE SCHNEIDER, a citizen of the Republic of France, and a resident of Paris, France, have invented a new and useful Improvement in Wheeled Gun-Carriages, which invention is fully set forth in the following specification.

In my application Serial N 0. 168,858, filed May 15, 1917, of which the present application is a division, I have described and claimed a wheeled gun carriage of the type adapted to slide on its axle for the purpose of training, in combination with means for elastically mounting the carriage on the axle without interfering in any way with the freedom of sliding of the entire gun carriage along the wheeled axle. This means. essentially consists of a box composed of two elements capable of sliding vertically relatively to each other, without relative longitudinal displacement. One element of this box is carried by the carriage and the other by the axle, metal or other springs being interposed between the elements of the box.

The present invention relates to a some- What difl'erent constructional form of the invention wherein the training of the carriage on the axle is effected by operating means which are in part carried by that element of the box which slides directly on the axle and in part by the carriage and that element of the box that is fixed to the carriage, the two parts being connected together through flexible connections such as a telescopic spring device and Cardan joints.

In the drawings- Figure 1 is a transverse sectional view through the axle of a wheeled gun carriage showing my improvements;

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1;

Fi 3 is a vertical longitudinal section on the line 33 of Fig. 1;

Fig. 4. is a cross-section on the line H of Fig. 3; and

Fig. 5 is a part section on the line 55 of Fig. 1.

Referring to the drawings, A is the gun carriage proper, constructed so as to be capable of sliding along the wheeled axle C. According to this invention, the guiding of the carriage A on the axle, in its sliding movement along the latter, is effected b means of a box composed of two elements B extending one inside the other in such a manner that neither can have any longitudmal movement relatively to the other, but 1s capable of sliding vertically one inside the other. Between these two box elements there are arranged springs D which may be of metal or otherwise.

In the constructional example shown in Figs. 1 to 5, the box element B that slides directly along the axle, carries projecting guide claws 6 (Figs. 1 and 2) for the ribs 6 formed on the box element B that is fixed to the carriageA. This mutual guide device bb b prevents all longitudinal displacement of the two box elements relatively to each other. One part of the mechanism for efi'ecting the sliding of the carriage along the axle is carried by the box element B another part of the mechanism is carried by the carri ge A and the box element B fixed to the latter.

The part that serves to provide a bearing or abutment of the mechanism upon the axle is in this case constituted by a rack c. That part of the mechanism that is carried by the box element B comprises a pinion L which engages with the rack c and has its axle Z journaled in the'said box element B The axle Z carries also a helical pinion M which engages with a worm N fixed on the shaft n j ournaled likewise in the box element B The shaft 7% carries further, on each of its ends, a beveled pinion N engaging with a pinion 0 whose axle o is journaled like the shaft n and the axle Z in the box element B The axle 0 carries further, the element P of a Gardan joint PP the other element P of which is carried by one of the short shafts Q of a telescopic device Q}Q.

The short shaft Q has a key 9 slidable in a slot 9 in the short shaft Q. A spring R bears at its ends respectively against the two shafts Q and Q. The short shaft Q carries at its other end, the element S of a Cardan joint SS the other element S of which is carried by the axle s j ournaled in a bracket a fixed to the gun carriage A and the box element B.

The axle s carries a pinion T engaging with a pinion U Whose axle u is journaled in the bracket a and carries a hand wheel V.

Gear NOTU and hand-operating Wheel V may be provided at each end of the shaft n.

The operation of the device will be readily understood from the above description. By rotating hand-wheel V, power is applied to drive shaft a mounted in the carriage frame and box element B through flexible shaft Q, g, and Cardan joints P, P and S, S to rotate worm gear N, thereby driving gears M and L mounted on the box element 13 Gear L is thereby caused to travel over rack c and move the carriage along the carriage axle.

What is claimed is 1. In combination, a wheeled axle having a slidable box element thereon, a gun carriage frame having a companion box element yieldingly mounted on said first-named box element and slidable therewith, mechanism for effecting the sliding of said carriage on the axle adapted to be carried in part by the box element mounted directly onthe axle and in part by the gun carriage and the companion box element, said mechanism including yielding power-transmitting means Copies of this patent may be obtained for five for connecting the separately supported parts of said mechanism.

2. In combination, a wheeled axle having a slidable box element thereon, a gun carriage frame having a companion box element yieldingly mounted on said firstnamed box element, mechanism for sliding said gun carriage along the axle comprising gear means mounted on the first-named box element and other gear means mounted on said carriage frame, and a longitudinally yielding power shaft having flexible connections with each of said gear means.

3. A device as claimed in claim'2 wherein said connecting power shaft consists of two short shafts slidable one in the other without angular displacement, aspring between said short shafts and the outer ends thereof having Card'an joints for connecting with said gear means.

In testnnony whereof I have signed this specification.

EUGENE SCHNEIDER.
